Clean the weld area and remove all plating or anodized finish. Try to leave a gap of 1/16" to 1/8". Bevel 60° to 70° where butt joints or cracks are involved. It is unnecessary to melt the base metal. Use a carburizing flame and heat the work piece by keeping the flame 1" to 3" from the surface. Touch FLUX-CORE to the weld area under the torch flame until the filler metal flows. Deposit small amounts of alloy and allow it to flow out on the weld area. For build-up work, reduce the heat and play the flame on the filler rod just above the workpiece and melt drops of the filler rod into the workpiece. Remove the flux residue with warm water and a stiff brush. Crimp the end of the rod after use to seal in any unused flux.
